Destroying the Bird
I don't play against the bird very often. However I have been playing the Dutch defense a fair amount lately, and the bird is a lot like the Dutch defense with colors reversed. So what I did shortly after the first move was ask myself, what annoys me most when I play the Dutch defense?
Thus my early Bg4, and ultimately the idea of castling queenside and bringing a pawn storm down the kingside. I think I played this very well, though computer analysis shows a few things that I could have done differently. Victory was ultimately due to white making a couple mistakes under the pressure of the pawn storm.
